Reboot Loops Xr

I have two iPhone XR’s that have suddenly both decided they want to randomly reboot themselves.

iPhone Xr Red - "panicString" : "panic(cpu 0 caller 0xfffffff00c5e3dd0): \"i2c0::_checkInterrupts

iPhone Xr Black - “panicString” : “panic(cpu 1 caller 0xfffffff01c8c3b7c): userspace watchdog timeout: no successful checkins from apple.thermalmonitord in 180 seconds missing sensor(s): TG0B TG1B

these phones were working just fine and both decided to just panic and restart themselves over and over again without warning for different reasons at the same time. This seems to be more than coincidental.
